Answer:
-1/3125, 1/625, -1/125, 1/25 , -(1÷5) , 1 , -5
Step-by-step explanation:
1÷625÷(-1÷3 125) = -5
-1÷125÷(1÷625) = -5
(1÷25)÷(-1÷125) = -5
Then the common ratio of the geometric sequence is -5 then we keep multiplying by -5 each time to get the next term:
(1÷25)×(-5) = -(1÷5)
-(1÷5)×(-5) = 1
(1)×(-5) = -5
3+9+8=20
20x1=20
That’s the answer
X the first account interest = x/100*2 = 2x/100
(x + 800)/100 * 4 =( 4x + 3200)/100
2x/100 + (4x + 3200)/100 = 92
2x + 4x + 3200 = 9200
6x = 6000
x = 1000
C is the answer
Answer:
9π, or 28.26
Step-by-step explanation:
The Arc of the semicircle is the circumference of half a circle.
The radius of the semicircle is 9, and the circumference of a circle is 2πr, so it is 2π9 = 18π. since this is a semicircle, it is half of that, so 9π, or 28.26, since π is 3.14 here
In my opinion I would pick the top for both answers
